CVE-2024-24831 is a security vulnerability classified as Cross-site Scripting (XSS) in the Premium Addons for Elementor plugin developed by Leap13. This plugin extends the functionality of Elementor, a widely used WordPress page builder. The vulnerability stems from improper neutralization of user-supplied input during the generation of web pages, which allows attackers to inject malicious JavaScript code into pages rendered by the plugin. The affected versions include all releases up to and including 4.10.16. Because the plugin is used in WordPress environments, which are often publicly accessible, an attacker can exploit this vulnerability by crafting a malicious URL or input that, when viewed by an unsuspecting user, executes arbitrary scripts in their browser context. This can lead to session hijacking, credential theft, or manipulation of the website content. The vulnerability does not require authentication, increasing its risk profile, and no user interaction beyond visiting a maliciously crafted page is necessary to trigger the exploit. Although no known exploits have been reported in the wild as of the publication date, the widespread use of Elementor and its addons makes this a significant threat. The lack of a CVSS score necessitates an expert severity assessment based on the vulnerability's characteristics and potential impact.

The impact of CVE-2024-24831 is primarily on the confidentiality and integrity of affected websites and their users. Attackers exploiting this XSS vulnerability can execute arbitrary scripts in the context of the victim's browser, potentially stealing cookies, session tokens, or other sensitive information. This can lead to unauthorized account access or further attacks such as phishing or malware distribution. Website content can be altered or defaced, damaging brand reputation. For organizations, this can result in data breaches, loss of customer trust, and compliance violations. Since the vulnerability is in a popular WordPress plugin, many websites globally are at risk, especially those that do not promptly update or apply security patches. The ease of exploitation without authentication or complex prerequisites increases the likelihood of attacks. Although availability is less directly impacted, secondary effects such as site defacement or injected malicious content can disrupt normal operations and user trust.

To mitigate CVE-2024-24831, organizations should immediately update the Premium Addons for Elementor plugin to the latest version once a patch is released by Leap13. Until an official patch is available, administrators should consider disabling the affected plugin or specific vulnerable components if feasible. Implementing a Web Application Firewall (WAF) with rules to detect and block common XSS attack patterns can provide temporary protection. Website owners should also enforce Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts. Regularly scanning websites for XSS vulnerabilities using automated tools can help identify and remediate issues proactively. Educating users about the risks of clicking on suspicious links and maintaining robust backup and recovery procedures will also reduce potential damage. Monitoring security advisories from Leap13 and the WordPress community is essential to stay informed about updates and exploit developments.
